Pet's info: Dog | Cavalier King Charles Spaniel | Female | spayed | 5 years and 6 months old | 17 lbs

I have biscuits made with whole wheat flour and other ingredients. How long will they be fresh for once opened? Is 2 years an ok amount of time to keep opened treats? (In a sealed container)

Properly stored, they may last about 8-12 months before becoming stale or contaminated. An air tight container in a dry, dark location is best. Freezing may extend shelf life, especially regarding homemade biscuits. I would hesitate to use biscuits that are two years old regardless of storage method.
